장애친화적 캠퍼스를 위한 교육복지시설에 관한 연구

The purpose of this study is to provide design guidelines necessary for creating disability-friendly campuses. To this end, a literature survey and a survey on the current educational welfare facilities for disabled college students were conducted. The fact-finding survey was conducted in writing and visiting evaluations on 19 campuses located in Gangwon-do(province). The results of this study are summarized as follows: 1) The college enrollment rate of the disabled has doubled since 2000, but it was found to be half of the enrollment rate based on school enrollment, and the number of students who gave up in the middle is increasing. This is due to an obstacle in the learning environment, so it is necessary to improve welfare facilities. 2) As a result of evaluating the status of educational welfare support for students with disabilities, it was found that the overall evaluation result was improved, but the absolute evaluation result was less than 70%, and it was not improved. 3) As a result of evaluating the actual conditions of the intermediate facilities, indoor facilities, sanitary facilities, guidance and other facilities, and unit spaces, it is necessary to expand and improve them due to the lack of disabled parking marks, continuity of access roads, pedestrian safety passages, lifts, and rest areas for the disabled.

Air Quality Index through Inverse Evaluation of Hazard Quotient for Public Indoor Facilities - schools, child daycare centers and elderly nursing homes

Indoor air quality indices (IAQI-S, IAQI-C and IAQI-E) were developed to manage air quality in public facilities for vulnerable groups such as schools, child daycare centers, and elderly nursing homes, respectively. In this study, hazard quotient (HQ) was first designated, then the concentrations of each pollutant were calculated by adding the exposure factor of residents. The presented index was more stringent than comprehensive air quality index (CAI) for outdoor atmosphere. Also, composite indices that integrate individual indices for each pollutant were developed for quick and convenient recognition of the current air quality by administration officers or teachers and to take remedial actions. Among all data collected in field measurements, 75.4%, 71.2% and 35.6% were classified as ‘Good’ or ‘Moderate’ in school classrooms, child daycare centers and elderly nursing homes, respectively

Distance to sports facilities and low frequency of exercise and obesity: a cross-sectional study

BackgroundLittle research has investigated the associations between proximity to physical activity facilities and behavior-related health and the majority have focused on proximity from home address. We add to the literature by examining proximity of these facilities to work and home address and including a wide range of physical activity facilities. We assess the associations for proximity of physical activity facilities from home and work address with self-reported frequency of exercise and obesity.MethodsOur analytical sample of 7358 participants was from the 2018 wave of the Swedish Longitudinal Occupational Survey of Health. We used logistic binomial regression adjusting for age, sex, education, civil status, individual socioeconomic status, neighborhood socioeconomic status, number of children under 12 years of age, work strain, and chronic disease.ResultsLonger distance from home to paid outdoor and paid indoor physical activity facilities was associated with low frequency of exercise (fully adjusted Relative Risk for both 1.01, 95% CI 1.01–1.02). Associations of any or free outdoor facility with low frequency of exercise were not robust. Findings also indicated associations between long distance from workplace to any and paid outdoor facility and low frequency of exercise. Results for obesity were in the similar direction, however, these were not statistically significant.ConclusionIncreased distance of paid outdoor and paid indoor physical activity facilities from home and of paid outdoor facilities from work was associated with low frequency of exercise. Longitudinal and larger studies are needed to confirm our findings, particularly regarding obesity.

Mobile phone indoor scene features recognition localization method based on semantic constraint of building map location anchor

Abstract Visual features play a key role in indoor positioning and navigation services as the main semantic information to help people understand the environment. However, insufficient semantic constraint information and mismatching localization without building map have hindered the ubiquitous application services. To address the problem, we propose a smartphone indoor scene features recognition localization method with building map semantic constraints. First, based on Geographic Information System and Building Information Modeling techniques, a geocoded entity library of building Map Location Anchor (MLA) is constructed, which is able to provide users with “immersive” meta-building-map and semantic anchor constraints for mobile phone positioning when map matching. Second, using the MYOLOv5s deep learning model improved on indoor location scenario, the nine types of ubiquitous anchor features in building scenes are recognized in real time by acquiring video frames from the smartphone camera. Lastly, the spatial locations of the ubiquitous indoor facilities obtained using smartphone video recognition are matched with the MLA P3P algorithm to achieve real-time positioning and navigation. The experimental results show that the MLA recognition accuracy of the improved MYOLOv5s is 97.2%, and the maximum localization error is within the range of 0.775 m and confined to the interval of 0.5 m after applying the Building Information Modeling based Positioning and Navigation road network step node constraint, which can effectively achieve high positioning accuracy in the building indoor scenarios with adequate MLA and road network constraint.

Identification of Bacteria and Fungi in Various Types of Multi-Use Facilities in Bucheon, South Korea

The recent sequential appearance of infectious pathogens has caused ongoing social and economic damage. Despite the very high potential for pathogen transmission within indoor multi-use facilities, there are insufficient measures for the systematic analysis, diagnosis, and reduction in such transmission. Although real-time environmental information is available for pollutants such as particulate matter, carbon dioxide, and nitrogen dioxide in South Korea, an automatic network for the real-time measurements of harmful microorganisms has not yet been established. Therefore, in this study, we analyzed the concentrations of bacteria and fungi in different types of multiple-use facilities in Bucheon, South Korea, using the analytic hierarchy process (AHP) method. All multi-use facilities in the region were classified into six types: facilities for pollution-sensitive groups (e.g., children or the elderly) and transportation-related, public transportation, temperature-controlled, food preparation, and other facilities. Next, the importance of each facility type in terms of bacterial and fungal abundance was evaluated using the AHP method, according to criteria selected using the AHP method. The highest importance was assigned to multi-use facilities for air-pollution-sensitive groups, which were associated with higher user density and more confirmed cases of COVID-19; the second-highest importance was assigned to public-transportation facilities. Bacteria detected at representative multi-use facilities were identified using 16S rRNA sequencing and included the human pathogens Bacillus anthracis, Bacillus cereus, Pseudomonas fluorescens, Erwinia billingiae, and Enterobacter cloacae. This study is the first to measure monthly and seasonal concentrations of bacteria and fungi at 30 multi-use facilities in Bucheon. The results of this study will be useful for designing systematic measures for the control of infectious bacteria and fungi in various types of multi-use facilities, according to their specific characteristics.

Husbandry, Captive Breeding, and Field Survey of Chinese Giant Salamander (Andrias davidianus).

The Chinese giant salamander (Andrias davidianus) is the largest extant amphibian species in the world with adults capable of reaching 2m in length. Wild populations of A. davidianus have declined dramatically during the last century, making it also one of the top threatened species globally. Fortunately, aquaculture for this species developed in China during the 1970s has been extremely successful. Many relevant commercial products of A. davidianus have been produced in recent years on account of its nutritional and medicinal values. Balancing conservation and utilization will be key to the future destiny of A. davidianus. In this chapter, we describe detailed protocols for husbandry in indoor and outdoor facilities, captive breeding under natural-imitative conditions and using artificial insemination, and surveying and monitoring A. davidianus in the field. The protocols presented here aim to make the practices of A. davidianus operative and increase public awareness of this mystical and precious species.

Assessment of the risk associated with chemical pollution of air environment of sports facilities for children’s health

Introduction. Acute and chronic exposure to chemicals is accompanied by a complex of disorders in the activity of the respiratory, immune and other systems. Purpose is to assess the health risk to children from short-term exposure to pollutants in air of out- and indoor sports facilities. Materials and methods. The air quality of ice arenas, sports halls for martial arts and sports halls in schools was studied using maximum samples; out-door air - according to the average monthly and maximum concentrations registered in 2017-2021. The risks of acute exposure for indoor and outdoor sports facilities are calculated. Results. Against the background of a single excess of the maximum one-time (in gyms) and average monthly (in the atmosphere) concentrations of chemicals, risks to the health of children involved in sports were identified. The maximum share contribution to hazard index (HI) for the respiratory system in the air of the ice arena is made by formaldehyde (58.3%), in school halls - by suspended solids (47.3%). The seasonal dynamics of pollution is revealed, which confirms the importance of thermal power emissions. The maximum Hazard Quotient (HQ) PM10 = 3.1-3.9 is established in winter, and in summer it is 3-4 times lower. The content of PM2.5 in the air is responsible for the extremely high risk in May (HQ = 12.5). The limitation of the results is due to the lack of indoor studies and insufficient knowledge on the impact of acute health effects. Limitations the results are due to the small number of indoor studies and insufficient knowledge about the impact of acute health outcomes. Conclusion. Further study of the short-term effects of indoor and outdoor air pollution from sports facilities is needed.

165 Environmental Concerns Identified Through an Anonymous Online Survey

Abstract Equine farms, typically, build either stables or barns for the horses to live in and additional facilities to train and work horses (Kidd, Winchell, & Burwash, 1997). Often these training facilities also include indoor riding arenas to ensure continuums in training programs. As the equine industry contributes a total of $122 billion dollars a year to the United States’ economy, it is important to research the farms and facilities that are built and used (American Horse Council Foundation, 2018). 71% of the 335 respondents of an anonymous online survey conducted in the summer of 2018 reported having environmental concerns in the indoor arenas they rode and trained in. The main environmental concerns were dust, moisture, and air movement, though light and temperature were also noted concerns. Analysis was conducted to examine the association of the environmental concerns with different aspect of the indoor arenas such as footing types, attachment to barn, presence of windows and wall openings, and temperature control mechanisms in the facility. A notable trend towards significance is the concern with air movement decreased with the presence of fans and temperature control mechanisms (p< 0.10), while significant associations between lighting concerns were impacted by the presence or absence of translucent panels (p< 0.05) and the number of lights in the indoor arena also impacted whether lighting was a concern (p< 0.05). Overall, dust was always a concern no matter the circumstances. As environmental concerns were expressed by the majority of respondents, it’s important to identify potential reasons for the issues and then work to mitigate the concerns. This involves more targeted research in the future, assessment of mitigation tactics, and resources to design and build indoor arenas and facilities in ways that minimize environmental issues.

An Approach for Lighting Calculations in Indoor Mirrored Facilities Based on Virtual Twin-Spaces

The presence of walls with different reflectance in indoor facilities is a problem when designing their lighting installations. This problem becomes more serious when one or more walls are mirrors, a common situation in medical, sport, educative and many other indoor facilities. Even if some programs can work with different approaches, the results are far from exact and, in many cases, designers ignore the mirrors and work by eye, with results that are frequently excessive in terms of illuminance on the working planes, glare and energy consumption and use of materials. These deviations from the intended results are due to the direct or indirect estimation of reflectance remarkably lower than 1 in the mirrored walls. In this framework of uncertainty, this work is presented with the objective of developing an intuitive theoretical model based on the consideration of virtual twin-spaces behind the mirrors. This proposal is not just an approach, but a useful tool providing the input for any kind of calculation ranging from the lumen method, used in quick pre-dimensioning, to the most complete calculations with computational methods. In addition, apart from calculating the number of luminaires and photometric parameters, the use of virtual twin-rooms also takes into account the extended field of vision of the users, including objects behind, and virtual luminaries. This advantage has no precedent in the literature up to date.

SPORTS AND RECREATION FACILITIES IN THE SYSTEM OF URBAN UNDERGROUND PUBLIC SPACES

Underground urbanism is an important way of developing sustainable cities, with an important component - the concept of "Healthy city", its part – sports and recreation. The article presents the results of graphoanalytic analysis of the existing location of outdoor sports grounds and indoor facilities in the pedestrian accessibility zone from the stations of the Almaty metro. These results can be taken into account when developing models of prospective functional and spatial development of the underground environment in connection with the development of the city of Almaty.

RURAL ECONOMY AND PHYSICAL WELLNESS: A THEMATIC REVIEW PAPER

India is a developing diverse country with diverse in people, society and religion. People living in urban areas where they get all facilities and services. Oppositely people living in rural areas get less of the resources and services. They are having fluctuations in literacy rate birth and death rate GDP NDP and so many things. The back ground of physical fitness is generally more than the urban areas because people involvement and profession make them fit and connecting nature. Although they are having a less sports resources but after that people are today enough aware about sports and they starts participations and today Govt. of India is giving facilities of games and sports in so many schools and collages so that children younger’s and elders are always filled with inner enthusiasm and generally this enthusiasm is seen in rural areas people. The games participation at state national and international level where their enthusiasm takes a platform. While in rural areas people are suffering with infrastructure facilities and products such as indoor and outdoor facilities of grounds. Such Schemes is run by Govt. India Rajkumari scheme, HVPM, LNIPE, NSNIS, SAI and so many institutes in India which was set up after Independence and Independence which works is to provide coaches, teachers, players, physiologist, physiotherapist, dietician and so many people today appears due to this institution and many of the brands today supports India’s economy like ‘ShivNaresh’ is one of the brand in sports.

Dust-Associated Bacterial and Fungal Communities in Indoor Multiple-Use and Public Transportation Facilities

Indoor microbes are readily transmitted among humans in indoor environments. Therefore, this study employed 16S rRNA gene and ITS amplicon profiling to investigate the dust-associated bacterial and fungal communities in six indoor facilities in Busan, South Korea. The collected samples were categorized into two groups: indoor multiple-use facilities (MUFs), including a public bathing facility, business office, and food court; and public transportation facilities (PTFs), including two subway stations and an airport. The bacterial diversity in the MUF samples was significantly higher than the fungal diversity (p < 0.05). However, no significant differences between bacterial and fungal diversity were observed in PTF samples (p > 0.05). Moreover, the abundances of certain microbial taxa varied, suggesting that the microbial community structure was primarily determined by the source environment. Gram-positive bacterial genera, such as Corynebacterium, Kocuria, and Staphylococcus—all of which originated in the natural environment—were relatively predominant in the MUF samples; the Aspergillus, Penicillium, and Malassezia genera, which are human commensal taxa, were relatively more predominant in the PTF samples. These results suggest that different microbial communities can be formed depending on the purpose of the indoor facility type, level of passenger traffic, and surrounding environment. The findings of this study may help researchers understand indoor microbial communities in multi-use and transportation facilities.

Detection and assessment of dust mite allergens in an indoor environment in Anhui, China

Dust in the home environment is thought to be a potential trigger for increasing allergic diseases, such as allergic rash, rhinitis, asthma, and other conditions, associated with dust mites. To verify the status of dust mite prevalence in indoor surroundings, we collected 189 dust samples from the air conditioner filters (n = 75) and floors (n = 114) of households, schools, and hotels in the Anhui area, China. All samples were measured for dust mite breeding rate and breeding density under light microscopy and analyzed for dust mite species Dermatophagoides farinae 1 (Der f 1) and Dermatophagoides pteronyssinus 1 (Der p 1) allergen using enzyme-linked immunosorbent assay (ELISA). The dust mite breeding rates were 34.67% (26/75) and 20.18% (23/114), respectively, in the dust samples from the floor and air conditioning filters. The breeding density was the highest in households (10/g), followed by schools (9/g) and hotels (4/g). ELISA indicated that the allergen threshold (2.0 µg/g dust) of Der f 1 was exceeded in only two samples and Der p 1 in one sample. Additionally, a questionnaire was used to investigate the health knowledge on allergic diseases involved in indoor facilities, finding that most allergy sufferers were aware that indoor dust might be responsible for their conditions. The findings suggest that regular maintenance of indoor hygiene and cleaning of air-conditioning filters should reduce the risks of exposure to indoor allergens.

Association of compliance with COVID-19 public health measures with depression

Although previous studies have demonstrated increased depression related to COVID-19, the reasons for this are not well-understood. We investigated the association of compliance with COVID-19 public health measures with depression. Data from the 2020 Korea Community Health Survey were analyzed. The main independent variable was compliance with rules based on three performance variables (social distancing, wearing a mask in indoor facilities, and outdoors). Depression was assessed using Patient Health Questionnaire-9 scores. Of 195,243 participants, 5,101 participants had depression. Bad and moderate performance scores for compliance were associated with depression (Bad score, men: adjusted odds ratio [aOR] = 2.24, 95% confidence interval [CI] = 1.29–3.87; women: aOR = 2.42, 95% CI = 1.42–4.13; moderate score, men: aOR = 1.31, 95% CI = 1.02–1.68; women: aOR = 1.28, 95% CI = 1.07–1.53). In the subgroup analysis, among the quarantine rules, not wearing a mask indoors was the most prominently associated with depression. In participants with a high level of education, non-compliance with quarantine rules was significantly associated with depression. People who do not comply with public health measures are more likely to be depressed. The preparation and observance of scientific quarantine rules can help mental health in the ongoing COVID-19 pandemic and another infectious disease pandemic that may come.

A Low-Cost and Efficient Indoor Fusion Localization Method.

Accurate indoor location information has considerable social and economic value in applications, such as pedestrian heatmapping and indoor navigation. Ultrasonic-based approaches have received significant attention mainly since they have advantages in terms of positioning with temporal correlation. However, it is a great challenge to gain accurate indoor localization due to complex indoor environments such as non-uniform indoor facilities. To address this problem, we propose a fusion localization method in the indoor environment that integrates the localization information of inertial sensors and acoustic signals. Meanwhile, the threshold scheme is used to eliminate outliers during the positioning process. In this paper, the estimated location is fused by the adaptive distance weight for the time difference of arrival (TDOA) estimation and improved pedestrian dead reckoning (PDR) estimation. Three experimental scenes have been developed. The experimental results demonstrate that the proposed method has higher localization accuracy in determining the pedestrian location than the state-of-the-art methods. It resolves the problem of outliers in indoor acoustic signal localization and cumulative errors in inertial sensors. The proposed method achieves better performance in the trade-off between localization accuracy and low cost.

The Impact of COVID-19 on Physical Activity and Life Satisfaction of Golfers: A Cross-Sectional Study in German-Speaking Countries.

Golf is an outdoor sport played worldwide, and golfers of all ages benefit from regular exercise and social contact. The COVID-19 crisis has led to lockdowns, curfews, and closures of golf courses and other indoor and outdoor sports facilities. This study aimed to retrospectively assess how golfers perceived the impact of the crisis on physical activity and life satisfaction. We conducted a cross-sectional online survey among 1,115 golfers (61% men, mean age 55.0 years) in German-speaking countries, mainly Austria and Germany, from March to June 2021. When comparing ratings before and during the COVID-19 period, participants reported exercising more indoors at home independently or with online instructions. Likewise, the popularity of exercising outdoors in publicly accessible open spaces increased overall, especially in rural areas by about 10%. Life satisfaction decreased significantly by 24.2% (p < 0.001) during the pandemic. From a public health perspective, access to outdoor sports facilities such as golf courses might alleviate the negative psychosocial and health effects of home confinement and restricted access to indoor sports facilities. Further research is recommended to evaluate the longer-term impact of COVID-19-related measures on the physical activity and life satisfaction of golfers.

UNCERTAINTY MODELING FOR POINT CLOUD-BASED AUTOMATIC INDOOR SCENE RECONSTRUCTION BY STRICT ERROR PROPAGATION ANALYSIS

Abstract. Accurate digital representation of indoor facilities is a key component for the generation of building twins. 3D indoor scenes are often reconstructed from 3D point clouds obtained by various measurement techniques, which usually show different accuracy characteristics. During the reconstruction process, the uncertainties of data and intermediate products propagate into the accuracy of the vectorized model. Although point clouds-based 3D building modeling has been a hot topic of research for at least two decades, a thorough analysis of error propagation for this problem from a geodetic point of view is still underrepresented. In this contribution, we propose an analytical approach to estimate the uncertainty of 3D modeling results using the analytic approach based on first-order Taylor-series expansion. A general model for the input data is established and the uncertainty expressions of all computed products are symbolically derived. We estimate the uncertainty of 3D data fitting, followed by the derivation of vectorized building parameters and their covariance matrices. The results of the theoretical approaches are tested on real data presenting an indoor scene. The practical example is illustrated, thoroughly analysed, and quantified.

Genetic Structure and Triazole Antifungal Susceptibilities of Alternaria alternata from Greenhouses in Kunming, China.

ABSTRACTAlternaria alternata is an opportunistic human fungal pathogen and a ubiquitous phytopathogen capable of causing diseases to >100 agricultural crops and ornamental plants. To control plant diseases caused by A. alternata, triazole fungicides have been widely used both in open crop and vegetable fields and in indoor growth facilities such as greenhouses. At present, the effect of fungicide use on triazole resistance development in A. alternata populations is not known. Here, we isolated 237 A. alternata strains from nine greenhouses around metropolitan Kunming in Yunnan, southwest China, determined their genotypes using 10 short tandem repeat markers, and quantified their susceptibility to four triazoles (difenoconazole, tebuconazole, itraconazole, and voriconazole). Abundant allelic and genotypic diversities were detected among these A. alternata strains. Significantly, over 17% of the strains were resistant to difenoconazole, and both known and new drug-resistance mutations were found in the triazole target gene cyp51. Our findings of high-level genetic variation of A. alternata in greenhouses coupled with high-frequency fungicide resistance call for greater attention to continued monitoring and to developing alternative plant fungal disease management strategies in greenhouses.IMPORTANCE Alternaria alternata is among the most common fungi in our environments, such as indoor facilities, the soil, and outdoor air. It can cause diseases in >100 crop and ornamental plants. Furthermore, it can cause human infections. However, our understanding of its genetic diversity and antifungal susceptibility is very limited. Indeed, the critical threshold values for resistance have not been defined for most antifungal drugs in this species. Greenhouses are known to have heavy applications of agricultural fungicides. In this study, we analyzed strains of A. alternata from nine greenhouses near metropolitan Kunming in southwestern China. Our study revealed very high genetic diversity and identified strains with high MIC values against two agricultural and two medical triazole antifungals within each of the nine greenhouses. Our study calls for greater attention to this emerging threat to food security and human health.

Understanding the Customer Experience and Satisfaction of Casino Hotels in Busan through Online User-Generated Content

Casinos contribute huge sums of tax revenues to local government, and influence the local economy greatly. Customer satisfaction of casino hotels is a key factor that affects overnight customers, when evaluating the casino as a whole. To find out the determinants of customer satisfaction, along with the relationship between the key factors, this study is based on 2897 reviews, focusing on casino hotels in the Busan area, and performs a series analysis. First, text mining techniques are utilized, in order to elucidate which words were mentioned most often in online reviews. Furthermore, the semantic network method as well as factor and regression analysis were conducted. According to the findings, the top 70 ranked keywords are grouped into four clusters: “Entertainment”, “Service”, “Facilities”, and “Atmosphere”. The results of exploratory factor analysis are grouped in five factors: “Location”, “Outdoor Facilities”, ”Indoor Facilities”, “Services”, and “Entertainment”. Within these five factors, “Location” and “Outdoor Facilities” showed significantly positive impact on customer satisfaction, while “Indoor Facilities” and “Entertainment” have a significant negative influence on customer satisfaction. As a result of these findings, theoretical suggestions and practical recommendations have been made, for helping to launch the future marketing strategies of Busan casino hotels.
